7 - PROTECTION FEATURES
Short Circuit and Over Current Protection
The PSB50/40/30 series is protected against short-circuit such that a short from any output to return shall not result in a fire
hazard or shock hazard. The driver shall hiccup as a result of a short circuit or over current fault. Removal of the fault will
return the driver to within normal operation. The driver shall recover, with no damage, from a short across the output for an
indefinite period of time.
Internal Over temperature Protection
The PSB50/40/30 series is equipped with internal temperature sensor on the primary power train. Failure to stay within the
convection power rating will result in the power supply reducing the available current (fold back) below the programmed
amount. The main output current will be restored to the programmed value when the temperature of the built-in temperature
sensor cools adequately.
Output Open Load Protection
When the LED load is removed, the output voltage of the PSB50/40/30 series is typically limited to 1.3 times the maximum
output voltage of each model.

9 - PHASE-CUT DIMMING
Dimming of the driver is possible with standard TRIAC-based incandescent dimmers that chop the AC voltage as
shown in Figure 3, or with ELV dimmers. During the rapid rise time of the AC voltage when the dimmer turns on,
the driver does not generate any voltage or current oscillations, and inrush current is controlled. During the on-
time of the AC input, the driver regulates the output current based upon the conduction angle. The RMS value of
the driver output current is proportional to the on-time of the AC input voltage. When operating with an
incandescent dimmer, the RMS output current varies depending upon the conduction angle and RMS value of the
applied AC input voltage. Figure 4 shows the typical output current versus conduction angle at nominal input
voltage.
Forward-phase (TRIAC) and reverse-phase (ELV) dimming work only at 120 Vac.
The PSB50/40/30 series offers Tri-Mode Dimming™ compatibility with both phase-cut (reverse-phase and
forward-phase) and 0–10V dimmers. Phase-cut dimming always has priority over 0-10 V dimming.

11 - 0-10 V DIMMING
The PSB50/40/30 series operate only with 0-10V dimmers that sink current. They are not designed to operate with
0-10V control systems that source current, as used in theatrical/entertainment systems. Developed in the 1980’s, the
0-10V sinking current control method is adopted by the International Electrotechnical Commission (IEC) as part of its
IEC Standard 60929 Annex E.
The method to dim the output current of the driver is done via the +Dim/-Dim Signal pins. The +Dim/-Dim Signal pins
respond to a 0 to 10 V signal, delivering 1% to 100% of the output current based on rated current for each model. A
pull-up resistor is included internal to the driver. When the +Dim wire (purple) is short circuited to the –Dim wire (grey)
or to the –LED wire (blue), the output current turns off.
If the +Dim input is > 10 V or open circuited, the output current is programmed to 100% of the rated current.
When not used, the –Dim wire (grey) and to the +Dim wire (purple) can be individually capped or cut off. In this
configuration, no dimming is possible and the driver delivers 100% of its rated output current.
The maximum source current (flowing from the driver to the 0-10V dimmer) supplied by the +Dim Signal pin is ≤ 1 mA.
The tolerance of the output current while being dimmed shall be +/-8% typical until down to 1.5 V.
The non-linear 0-10V dimming profile is the default profile across all models of the PSB50/40/30 series. In the non-
linear 0-10V dimming profile, shown in figure 5, 10V to 9.1V=100% of the output current, 1.5V to 0.6V=1%,
<0.6V=dim-to-off (no output current). The non-linear curve is recommended when using standard in wall 0-10 V
logarithmic dimmers to avoid having insufficient source current available to pull the dimmer up to 10V and to account
for the inability of the dimmer to pull below approximately 0.9V. In these type of installations, the modified transfer
function will ensure 100% light output and dimming to 1%, regardless of the number of drivers on the 0-10V dimming
line. Please contact your sales representative or send an email to: SaveEnergy@erp-power.com for additional
information.

13 - PROGRAMMING
The PSB50/40/30 series can be programmed by inserting the audio jack of the cable shown in figure 6 into the driver
and by plugging the USB other end of the cable into a computer. The driver does not need to be powered on
during the programming process.
When ordering the PSB50/40/30 series, please make sure you order a programming cable. The part number for the
programming cable is “PROG-JACK-USB”.
Programming is done by using the ERP GUI (Graphical User Interface) which enables to trim or adjust output current
from 100% to 50%.
Furthermore, when connecting the driver to a computer using the programming cable, you can access the driver’s
internal data log and read the following information: SKU, serial number, manufacturing lot code, hours of operation,
firmware revision, and fault events: power failure, transients (short or surge), thermal events (i.e. number of times the
case temperature has exceed the maximum case temperature of 90°C).
For more information, please refer to the GUI user’s manual.
